Be it known that it, Hanna cinnati, in the county of l n or" @hio, have invented oer aizi nsetul Tm rovements in v ord-Pranting vices, 01 which the following is specification. r

The device of this invention designed primarily as an attachment for addii chines with a view of providing mes the printing of words or abbreviations 1 of which are ordinarily used in making out statements, posting ledger sheets, or any work where designations are needed in addi. tion to the numeral figures to maize an intelligent record. For the printing of such designations, a type wheel is employed which is operated by first rotating the wheel to bring the desired designation to the proper position to approach the printing line, and thereafter actuating the mechanism provided for carrying the wheel to the printing sition.

The present invention is directed to the mechanisms for controlling these operations, and for so interlocking the respective mechanisms that neither'can be operated during the period of operation of the other, thereby ensuring correct manipulation of the device.

A further object is to provide means which will prevent the shifting of type from proper printing position or alignment, during the manipulation of the operating mechanism; and a further object is to provide means for the rapid-restoration of the setting devices to the current-or most com monly used designation.

The parts comprising this device are arranged in front of the platen and inking ribbon, so that the type which are held in the printing cylinder may be selected by means of the setting mechanism, after which the printing cylinder or wheel will be swung to imprint the desired designation on the paper backed by the platen, the inking ribbon heing interposed in the usual manner between the type and paper.

In the drawings, the device is shown as applied to a Dalton adding machine, although it is understood that the device is capable of general application and may even he usedindependently of an adding machine in cases where only a limited numher of printed designations are required.

The printing cylinder 10 is provided upon its periphery with logotype 11 which are preferably in number sufficient to indicate the months of the year, together with such designations as 1, Dn, Bal, etc. The type cylinder is journaled at the upper end ofa swinging frame comprising an inner arm 12 and an outer arm 13 in spaced relation to one another, the inner arm being provided with an ofiset or shoulder 14: to afiord working space for the type cylinder. The arms 12 and 13 are carried by a hub 15 journaled upon a bearing pin 16 projecting inwardly from a fixed plate 17 forming part of the rigid frame of the device. The two arms of the swinging frame are further connected by means of a cross pin 18 which, together with the hub 15, serve to afiord the necessary rigidity. The type cylinder is rigidly mounted upon a shaft 19 which carries a spur pinion 20 having teeth equal in number to the type on the periphery of the type cylinder. The shaft also carries a ratchet wheel 21 likewise having the same number of teeth. The type cylinder, spur pinion and ratchet wheel are in rigid relation to one another and rotate as a unit with the shaft upon which they are mounted L The means for imparting rotative move ments to the cylinder and the associated elements will now be described. The spur pinion 20 meshes with an intermediate idle pinion 22 which, in turn, meshes with a similar operating pinion 23, all of the said inions having the same number of teeth. T e pmion 23 meshes with a rack 24 secured to the inner face of a setting lever 25, which latter is bifurcated at its lower end 26 to engage a circumferential groove 27 in the periphery of the hub 15, which thus serves as a bearing for the setting lever and permits rocking thereof.

It will thus be seen that, as the setting lever is moved, it will rotate the type cylinder to a degree necessary to bring t e selected type to the printing line, the degree of oscillation being indicated by the lns'criptions on an indicator plate 28 secured to t e front cover plate 29 which is provided with a slot 30 through which the setting lever projects.

In order to properly center the type during the setting operation, a square lug 31 .is provided which stands in position to present one of its angles to the operating spur pinion 23, and said lug is mounted upon an L-shaped detent arm 32 which is pivoted upon a stud 33 inwardly extending from a side plate 34 which is connected with the outer side plate 17 by cross bolts 35, the inner and outer plates furnishin a rigid side frame for the housing of t e operating mechanism.

The detent arm 32 is provided at its outer end with a tongue 36 which receives the end of a spring 37 secured to a portion of the inner side plate, the arrangement being one which causes the square stud 31 to normally engage the recesses between the teeth of the operating spur pinion 33, and thereby act as a centering device to hold the gear train and with it the type cylinder in proper positions of adjustment so long as the gear train is unbroken, it being understood that as the type cylinder is swung toward the platen, the gear train will be broken so that other means must be provided during this'stage of the operation for preventing displacement of the type cylinder from its adjusted position.

The means for advancing the type cylinder to the printing line will now be described. As best shown in Fig. 3, the outer side plate 17 is provided with an upstanding arm 38, which has pivoted thereto an operating lever 39 provided with a finger button 40 within convenient reach of the operator. The lever 39 is provided with a slot 41 which receives a pin 42 carried by a rocking lever 43 which is fulcrumed on a pivot pin 44 secured to the outer fixed plate 34.

' The lower end 45 of the rocking lever is positioned to engage a stud 46 on the arm 12 so that as the operating lever 39 is dein its previously adjusted position. Theratchet wheel 21 co-operates with a detent 47 which is pivoted to the pin 18 connecting the swinging arms 12 and'13, which detent, at its lower end, is provided with a laterally extending ear 49 which is adapted to ride upon a cam surface 50 constitutin the up per edge of a projection 51 upstan ing from the side plate 34. The detent is held against the ratchet wheel by the action of a spring 52, and when the operating lever is depressed, the ear 49 will advance along the cam edge 50, which contact of parts serves to lock the detent within a selected notch in the ratchet wheel, so that an rotative movement of the type wheel will be prevented during the printing 0 eration.

Upon the release 0 the operating lever, however, the ear 49 will be carried back sufficiently to clear the cam edge 50 so that during the setting operation, the detent may ride in and out of the notches in the ratchet wheel as the type wheel is being rotatively adjusted. During the course of such adjustments, however, as the upper end of the detent rides over a tooth in the ratchet wheel, its lower end will be depressed as indicated in Fig. 6, which depression will bring the ear 49 below the cam edge 50, so that during this intermediate stage of setting-up operation, any effort to depress the operating key and advance the type cylinder will be futile by reason of the fact that the engagement of the ear 49 with the forward edge of the projection 51 will lock the parts against printing operation. It must be seen. that coaction of the setting-up and printing mechanisms is such that the two operations must, of necessity, be performed in roper sequence to one other.

11 order to prevent idle movement of the setting-up gears durin the printing movementof the type whee and while the gear train is disengaged, the following mecha nism is provided: The rocking lever 43 has formed thereon an inturned ear 53 which coacts with the rear edge 54 of the detent 32, which latter is provided with a notch 55 at a point immediately adjacent the position of the ear 53. During the setting-up movements, when the square pin 31 rides out upon a tooth of pinion 23 (see Fig. .6), the ear 53 will lie sufiiciently within the notch 55 to prevent a depression of the opto position opposite the thumb-so crating hey, irrespective o the ear with the projection however, the square 3i rides notch on the gear wheel, the detent will move inwardly sufficiently to permit the car 53 to clear the notch and ride upon the 54, so that with the parts thus positioned the operating key may be actuated. During the operating movementcd the hey, the engagement of the car 53 with the will positively lock the square pin 31pm the selected gear notch so that printing operation an effort to move the setting-up lever will be futile, and the will stand in proper relation to remesh v one another upon the return movement the type cylinder with the gear carried thereby.

A spring 56 secured to one to the arm 19; and at its opposite end to the pl serves to return the type cylinder d a sociated parts to normal position printing operation, and in 0rd" tats a return of the setting-up current or usual position, a knurled screw 5'? is adjust-ably mounted slot 58 adjacent the setting-up lever, so t the thumb-screw can be clamped c" the im'licationoi the cm any other convenient pos tion, and ting-up lever can be quickly broa merely placing the thumb and foreii" the knurled thumb-screw st lever button respectively, and then pinching the thumb and finger together in easy and convenient manner,

The operation oi: the device may be briefly summarized as follows: in order to print a selected designation the settingnp lever will be first moved to the necessary degree to bring the setting-up lever into register with the item indicated on the indicating plate; thereafter the operating lever will m depressed to carry forward the adjusted type cylinder to the printing line. Intermediate adjustments of tie setting-up mechanism are prevented by means of the detent mechanism, and an attempt 'to'depress the operating lever uring intermediate stages in the setting-op operation will be prevented by the interlocking or the parts in the manner described. After an item has been properly set up, and during the ad- Vance of the cylinder to "the printing line, maladjustment thereoi is prevented by the locking of the parts, and during the same interval any manipulation of the se tin -up mechanism which would have the effect of interfering with a proper registry of the gears on the return movement is lilrewise prevented by the described interlock be tween the setting-up and operating mecha= msms.

As indicated in Fig. 2, two type cylinders eithe one in re such mechanisms may be provided onan or other similar machine as occasion may resume attacned s adding machine of standard in such position as to'interiere in no way with operation of the type sectors or other mechanisms which are employed or recording" numbers intended correspond or register with the designations mpressed by tLe printing mechanism heren described I claim:
